           Summary: ipset fails to parse port names with hyphen for
                    bitmap:port type
           Product: ipset
           Version: unspecified
          Platform: All
        OS/Version: Debian GNU/Linux
            Status: NEW
          Severity: normal
          Priority: P5

Overview: 
The problem is seen with adding port names that contain a hyphen, to an ipset,
for example http-alt or snmp-trap. It seems that the ipset command is treating
it as a range. 

Steps to Reproduce:
1. Create an ipset that uses bitmap:port of range from 1 to 65535. 
2. Add a portname to this ipset using ipset -A. Use a port name that has
hyphen, for example http-alt.  

Actual Results: 
ipset threw an error, "ipset v6.11: Syntax error: 'alt' is invalid as number". 

Expected Results: 
ipset should add port 8080 to the list of members. 

Build Date & Platform:
Initially saw it on 6.9. Tested again on 6.11 on Debian Sid, testing. 

Additional Builds and Platforms:
Don't know. 

Additional Information: 
pasting output of my testing here.
